Roasted Potatoes and Green Beans is the ultimate one-pan side—crispy, cheesy, and packed with flavor! Tossed with fresh garlic and Parmesan, Yukon Gold potatoes turn golden and crisp while green beans roast to tender perfection.
Add the potatoes to a large bowl and pour two-thirds of the oil mixture over the potatoes, reserving the remaining third for later use. Toss to coat. Sprinkle potatoes with ¼ cup grated Parmesan cheese, and toss again until well coated. Line a large baking sheet with parchment paper and spread potatoes out in a single layer. Bake for 18 minutes.
1 ½ pounds Yukon Gold potatoes
In the same large bowl, add the green beans and drizzle with the remaining olive oil-mustard mixture. Toss to coat. Add 2 tablespoons grated Parmesan cheese and toss again until well coated. Push the potatoes to the side of the sheet pan and add the green beans in a single layer. Return to the oven and roast for 10-15 minutes, or until the potatoes are fork tender and the green beans are blistered.

Notes
Crispier Potatoes: For extra crispy edges, flip the potatoes halfway through baking and spread them out in a single layer to avoid steaming.
Meal Prep: Chop the potatoes and green beans up to 24 hours in advance and store them separately in airtight containers. The marinade can also be mixed ahead and refrigerated.
Storage & Reheating: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven at 375°F for 8-10 minutes or in an air fryer at 350°F for 3-5 minutes to keep the texture crispy. The microwave is an option but will soften the potatoes.
